Abstract

aparelho e método de recepção [problema] o objetivo da presente invenção é manter boas características de recepção enquanto também reduzindo escala de circuito tão pequena quanto possível em um dispositivo receptor para receber uma pluralidade de ondas radiodifundidas de bandas de frequência diferentes. [solução] uma primeira unidade de processamento de alta frequência (320s, 320t) detecta uma primeira onda radiodifundida transmitida usando uma primeira banda de frequência a fim de extrair um primeiro sinal de alta frequência. além disso, uma segunda unidade de processamento de alta frequência (320t, 320s) detecta uma segunda onda radiodifundida transmitida usando uma segunda banda de frequência que é diferente da primeira banda de frequência a fim de extrair um segundo sinal de alta frequência. então, pelo menos um oscilador local (320) gera um sinal de oscilador local usado na primeira unidade de processamento de alta frequência e na segunda unidade de processamento de alta frequência.Receiving apparatus and method [problem] The object of the present invention is to maintain good reception characteristics while also reducing circuit scale as small as possible in a receiving device to receive a plurality of broadcast waves of different frequency bands. [solution] a first high frequency processing unit (320s, 320t) detects a first broadcasted wave transmitted using a first frequency band in order to extract a first high frequency signal. In addition, a second high frequency processing unit (320t, 320s) detects a second broadcast wave transmitted using a second frequency band that is different from the first frequency band in order to extract a second high frequency signal. then at least one local oscillator 320 generates a local oscillator signal used in the first high frequency processing unit and the second high frequency processing unit.
